摘要：Natural dyes are considered as sustainable and eco-friendly dyes. They can produce different shades of colours and have lower colour fastness than synthetic dyes. The products of natural dyes are very much in demand due to their ability to produce different shades and eco-friendly nature. The normal method to produce natural dyes from plants is by boiling in water and the coloured extract produced is dyed on fabric The colurs of natural dyes from plants come from leaves, barks, roots, fruits or berries. In this study, waste from Gluta aptera wood (Rengas), obtained from Wood Engineering Laboratory at Forest Research Institute of Malaysia (FRIM), was tried and used as natural dye source due to the colour of the wood which is blood-red. The boiling and solvent extraction methods were used to obtain the dyes. The extracted dyes were applied on silk and cotton fabrics and their comparison in term of colours and shades on substrates, method of extractions as well as their ability to witstand washing, light and perspiration were compared.
